MSI MAG B850 TOMAHAWK MAX WIFI II — AM5 ATX with two PCIe 5.0 M.2, Wi-Fi 7 and 5G LAN

AMD B850 · AM5DDR5 · 4 DIMM · up to 256GBPCIe 5.0 x16 + 2x PCIe 5.0 M.2Wi-Fi 7 · 5G LAN

The MSI MAG B850 TOMAHAWK MAX WIFI II is an ATX motherboard for AMD Socket AM5 with the B850 chipset, made for Ryzen 9000, 8000 and 7000 desktop processors in gaming and all-round builds.

It offers four DDR5 slots (up to 256GB, EXPO), a PCIe 5.0 x16 graphics slot, four M.2 sockets — two of them PCIe 5.0 x4 from the CPU — Realtek 5G LAN, Wi-Fi 7 with Bluetooth 5.4, ALC4080 audio and eight fan/pump headers.

Before you order: Using the M2_3 socket drops the PCI_E3 slot to x2 (you can force x4 in BIOS, which disables M2_3). Ryzen 8000 processors run the main slot at PCIe 4.0 x8 or x4. Wi-Fi 7 and Bluetooth 5.4 need Windows 11 24H2.

What's in the Box

  • MSI MAG B850 TOMAHAWK MAX WIFI II motherboard (ATX, 30.48 x 24.38 cm) with pre-installed Wi-Fi 7 module
  • Wi-Fi antenna and accessories as packed by MSI — the exact accessory list is not published on the specification page
  • No CPU, memory, cooler or SSD is included

What It Means in Practice

  • Two CPU-attached PCIe 5.0 x4 M.2 sockets let you run two Gen5 NVMe SSDs at full speed with Ryzen 9000/7000.
  • Three rear USB 10Gbps Type-C ports plus a 20Gbps front Type-C header cover modern peripherals and cases.
  • 5G LAN and Wi-Fi 7 (320 MHz channels on 6 GHz) remove the need for an extra network card.
  • Seven fan headers plus a pump/system header make it easy to cool a high-end Ryzen quietly.

What Will Not Work

  • Intel processors and AM4 Ryzen — AM5 only.
  • DDR4 memory — DDR5 non-ECC unbuffered only.
  • Video output without a CPU that has integrated graphics.
  • USB4/Thunderbolt — this board has no USB4 ports.

Frequently Asked Questions

Is this the same as the original B850 TOMAHAWK MAX WIFI?
No. This is the WIFI II version (part 7E62-015R); check that the part number matches if you are replacing a board.
Can it run two Gen5 SSDs?
Yes, M2_1 and M2_2 are both PCIe 5.0 x4 from the CPU with Ryzen 9000/7000.
Does it have USB4?
No. For USB4, look at X870/X870E boards.
Singular Expert Insight · Buyer's Guide
The TOMAHAWK MAX WIFI II gives most of what an X870E board does — Gen5 graphics and two Gen5 SSD sockets, 5G LAN and Wi-Fi 7 — without USB4. Pair it with a fast DDR5 memory kit with EXPO.
✓ Buy it if you want a full-ATX AM5 board with strong storage and networking and do not need USB4.
✕ Skip it if you need USB4/Thunderbolt-class ports or a Micro-ATX size.
→ Also consider Gigabyte X870E AORUS ELITE X3D if you need USB4.
